Problem: hover effect does not work on all pages.

Installed: zen 1.3.8 NEW Clean install
Installed: IH2

I cant get all the pictures to come up.
The picture resize engine only hovers pictures in "sidebox review" and on "product details page(in additional pictures ex: picflower_morepics.jpg)"


Tried 3 installs:
First install was made over classic template.
Second install was made over APPLE ZEN template.
Third install(listed in installation order) was CLEAN INSTALL(where the public_html was wiped out, zen1.3.8 reinstalled, but database linked was old database file),than IH2 reinstalled.


I figured i have to add code to the pages like "all product" and "new products".
What type of code am i adding?

Thank you for input.
Your advise is greatly apprecieated.
